"Coffee machine"

The innovation concerns a coffee machine and deals especially with the heat exchange system of such coffee machines *

Coffee machines are known which have several pouring units and = a single kettle · '? in which a single coil superheater tube is built in; This ScWangeriüberhitzerföhf biidet the Viärmeaauschauscher that the heated water to the Spout unit delivers * With the well-known single coil overheat tube are the ones supplying the outfitting units Combine derivatives.

An essential part of the well-known Käffefriaschiileil consists därifif that a measure of measurement is difficult * because the " WälrmeaUs'täUsnahf each in its "construction to the needs the coffee machine or the count of the dispensing units is. On the other hand, it causes constipation of the only one Schiängenübefhitzerföhres an interruption in operation *

It is a goal of the innovation »the disadvantages described to be eliminated * According to the innovation, the coffee machine is characterized by a kit-like structure * whereby a plurality of identical heat exchangers in one common Boilers are arranged and each heat exchanger has a coil overheater tube and the associated boiler cover is provided with a two-way cold water inlet and a one-way hot water outlet * where the latter is connected to a spout unit and the different pouring units are connected by down conductors that end at the two-way connections »

Thin the innovation will be a considerable simplification in the Construction of the coffee machine achieved. The: modular construction of the heat exchanger facilitates the manufacture of the coffee machines and operational safety is also significantly increased.

In the drawing is an embodiment of the innovation shown schematically it show:

In Fig. 1, (KA) denotes a boiler on which, as is known) some connections are attached * such as the connections (RR) - (RA) ₍ the water level indicators (not shown in detail) are connected. As is known) one is Path (PR ") of the two-way connection (RR) usable for steam extraction *

The boiler has a cover flange (KO) on which the cover (GO), which carries the heat exchanger, is secured by a rubber seal Can be attached waterproof *

Two connections (AC) - (CA) are watertight on the cover (GO) attached, the connection (AC) for the inlet of cold water and the connection (CA) for the outlet the hot water is used * The connection (CA) and the relevant Spout units (GR) are connected by pipelines, as can be seen in particular from FIG.

The pouring water flows through the coil superheater pipe (SE) or the other superheater pipes (SE 'or SE) Heat exchange from the boiler water heated in the boiler. The boiler water in turn, it is heated by an electrical resistor (RI) or by the resistors (RI ") or (RI) and held at a predetermined temperature by a thermostat not shown in detail.

If one is provided with two spout units (GR) - (GR ') Coffee machine is provided * is the water inlet connection (AC) designed like a two-way connection and consequently a discharge line (TU) is provided, which connects to the cold water inlet connection (AC) is hydraulically connected to the corresponding pouring unit (GR '). The same applies to the third, fourth Spout unit etc.

The 'picture according to F ¹ Ig. 3 is more schematized and allows the application principle of the innovation to be better "understood"

It is clear that with the new one a dull ⁴ mohfefe pouring unit can be switched off without having to interrupt the operation of the whole coffee machine.
